The worm gear reducer is a power transmission device that uses the speed converter of the gear to reduce the number of revolutions of the motor to the required number of revolutions and obtain a machine with a large torque. Its traces can be seen in the transmission system of all kinds of machinery, from ships, automobiles, locomotives, heavy machinery for construction, processing machinery and automated production equipment used in the machinery industry, to common household appliances in daily life. , clocks, etc. Proper maintenance and use of the worm gear reducer can maximize its function. The following is a general summary of the installation and maintenance precautions of the worm gear reducer, hoping to help friends who use the reducer.

Precautions before installation

1. The mounting shaft should be cleaned before use. And check whether there is any bump or dirt on the installation shaft, if there is any, it should be cleaned up.

2. The operating temperature of the reducer is 0 to 40 °C.

3. Check whether the matching size of the hole (or shaft) connected to the reducer meets the requirements. The tolerance of the hole should be H7 (the tolerance of the shaft is H6).

4. Before use, replace the blockage at the highest position with the exhaust plug to ensure that the gas in the reducer is discharged when the reducer is running.

Installation of reducer

1. The reducer can only be installed on a flat, shock-absorbing, torsion-resistant support structure.

2. Under no circumstances should a hammer be used to knock the pulley, coupling, pinion or sprocket onto the output shaft, as this will damage the bearing and shaft.

Use and maintenance

1. After the reducer is installed, check whether it is flexible. Please carry out no-load test before formal use, and then gradually load and run under normal operation.

2. The reducer is strictly prohibited to exceed the rated load.

3. The reducer should check whether the oil level is normal before use and during work. Generally, lubricating oil has been filled before leaving the factory.

4. The breathable nut has been tightened in order to prevent oil leakage during transportation. It needs to be loosened during operation. It is strictly forbidden to use it without loosening.

5. During use, when it is found that the oil temperature is too high (over 80 ℃), and there are abnormal noises, etc., stop using it immediately and check the cause. You can continue to use it after troubleshooting or changing the lubricating oil.

If it is extremely cold, such as below -10°C, the influence of the ambient temperature on the reducer should be considered when selecting models, and configurations such as electric heaters can be considered. This is very important for the lubrication and maintenance of the worm gear reducer. Regularly observe the oil level trend , Observe whether there is any abnormality in noise and vibration.

The oil change system

The first oil change is to replace the lubricating oil after the reducer runs for 200-400 hours, and the subsequent oil change interval is less than or equal to 4000 hours to replace the lubricating oil. In the workplace with harsh working environment, high temperature and large dust, the lubricating oil should be checked every half a month. If the lubricating oil is dirty, replace the lubricating oil to keep the lubricating oil clean and prolong the service life of the reducer,Improve economic efficiency.

Oil replacement

1. When changing the oil, wait for the reducer to cool down and there is no danger of burning, but it should still be kept warm, because after complete cooling, the viscosity of the oil will increase and it will be difficult to drain the oil.

2. The reducer should use gear oil of a fixed brand and number, and should not mix different brands, brands or types of oil. During the oil change, the inside of the reducer should be cleaned first, and then new oil should be injected.
